MOP-WRINGER.

To all whom it may concern:

Be it known that I, MILTON E. DAVIS, a citizen of the United States,residing at Canastota, in the county of Madison and State of New York,have invented certain new and useful Improvements in MoplVringers, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

My invention relates to an improved mopwringer, and I declare thefollowing is a full, clear, concise and exact description thereof,sufiicient to enable one skilled in the art to make and use the same,reference being had. to the accompanying drawings in which likereference characters refer to like parts throughout.

One of the principal features of the invention is that the device isconstructed on such principles that itsoperation is equally eflicient inwringing mops of different sizes. This is accomplished by providing inthe series of members by which compression is effected a resilientmember, or members, whereby the compression is, beyond a given point, ofa yielding nature. So that if the mop is of large size the latter partof the movement by which pressure is applied is made against the partsof the mechanism which have the qualities of resiliency, while in thecase of a small mop the same parts are effective to compress it in thesmaller space which it occupies.

There are various other features, such as the construction, mounting andconnection of the moving presser, the presser-back, the bottom and otherparts.

In the drawings Figure 1 is a perspective view of one style of machine,one of the side frames being removed. Fig. 2 is a detail view of part ofthe side frame of Fig. 1. Fig. 3 is a perspective view of a modifiedform of construction of certain parts. Fig. 4. shows a detail of a partof Fig. 3. Figs. 5 and 5 are views of the modified constructions. Fig. 6shows a construction with two springs. Fig.7 is a side view of a furthermodification, of which Fig. 8 is a top view. Fig. 9 is a detail view ofthe back and presserback. Fig. 10 shows a style ofconstruction havingarms disposed at different angles on the shaft. Fig. 11 shows in detaila form of connection between two parts.

showing pins on the presser and presserback engaging in the bottomboard.

It is to be understood that various of the modifications shown can begrouped in such combinations as may be desired.

Referring to the figures in detail, A, A represent side frames orbrackets, preferably of metal, having means whereby to support thewringer on a pail or tub, such as prongs A.

B is the back, with which the brackets A are firmly connected bysuitable means. At the opposite or front part of the brackets they aresufficiently secured together by shaft C which has each end mounted onone of the brackets, though other or additional means may be employedfor the rigid connection of the brackets. The back B has what may betermed a presser-back, or a false-back, 1, loosely mounted on it withresilient members, such as springs 2, between the two whereby thefalse-back yields to pressure of the mop, thus increasing the resiliencyof that pressure whereby the de vice is adaptable to various conditions.The springs may be secured to the back and the presser-back to affordthe sole support of the latter. If desired, however, there may be otheror additional means used, such as pins 3, Fig. 9, shown as mounted onthe presser-back and extending through bores therefor in the back.

The presser-back is designed to form one of the boundaries of the spacein which the mop is compressed and, therefore, extends a sufiicientdistance toward the top of the device and toward the side frames. It isprovided with leakage bores, as indicated by 10. It is also extendednearly to the bottom piece D. This bottom piece may be mounted indifferent ways. In Fig. 1 it is shown having pins 4 supporting it on thebrackets A, though screws or other suitable means may be providedtherefor. This holds the bottom rigidly in place. I11 Fig. 3, a singlepin, screw or the like, 5, is shown, holding it at one edge to thebrackets so that the other edge can tilt, being held by any suitablemeans, such as pins, 6, or the like, extending through slots 7 in thebrackets. If preferred, a clip 8, Figs. 9 and 12, may be fixed to thebottom or the back, the other end loosely engaging the other member topermit the swing of the bottom. The bottom may be of wood or metal, asalso other parts,

provided with apertures, such as slots 9, presser may be extended tostrengthen it Fig. l, for proper drainage.

The presser is shown by E and forms the side of the compression spaceopposite the presser-back l and extends a suitable distance toward thesides, bottom and top. It is actuated by mechanism to be described, bywhich it is partially supported in place. A variety of means are shownfor guiding and holding it. In Fig. 1 slots 9, or certain of them,provide ways for the travel of fingers 11, certain of which may beheaded, as seen at 12, and which guide the presser in its movement andhold it in place. The fingers which are not headed are such as are shownin Fig. 3. Such pins 12 may also serve to support the bottom D in theconstruction wherein the presser is held up by pins 13 traveling inslots 14 in the brackets, Fig. 8. The pins 12 afford a hinge-likeconnection between the presser and the bottom, allowing the one to slideon the other, one or the other being supported in some manner such asindicated in the different illustrations, the design being to allow thepresser freedom of tilting as it moves to and fro while the bottom mayalso be mounted to allow it some freedom of movement. In case thepresser is suitably confined or guided, as by pins 13, it is notnecessary to use the headed pins 12 for such purposes, the bottom beinggiven some other suitable support. Such pins, however, have the furtherfunction of preventing the mop from being wedged between the bottom andthe lower edge of the presser as it is moved to and fro. Thisrequirement is also met by pins 11 in the presser and the presser-back,which need not, however, extend through the bottom but only into slots 9out part way through, as seen in Fig. 8. Such pins may be used in theform shown in Fig. 1 being intermediate of pins 12 and traveling inslots 9 and extended as far therein or therethrough as neeclful. Thepresser also has leakage bores, such as 15 and the slots 9 should alsobe cut through at points for drainage, as at 9 It will thus be seen thatI have provided a space for the mop, with a bottom and sides, severallyprovided with drainage openings, mounted in a more or less flexibleconnection, the sides being adapted to tilt in adapting themselves tothe mass to be compressed and so interfitted with the bottom as toprevent wedging where that is liable to occur.

The shaft C is suitably mounted in the frames or brackets. It isprovided with one or more arms, 20, suitably secured thereon or integraltherewith and properly positioned. At 21 is shown one or more linksconnected with the arms, the other end bearing on the presser which hasa cleat, or cleats, 22, adapted to receive and hold the links. Thecleats 22, being secured to the and distribute the strain ofcompression. The cleats each have an eye 23, the links being headed toslip into the eye, and to be held therein when the parts are assembled.

An important feature of the invention is that between the shaft 0 andthe presser I and as part of the mechanism which operates the latter,there is a resilient member, or a plurality of them, such as the springsshown, the arm and link being connected in any suitable slidingengagement, so that when pressure is applied to the mop, especially atthe latter part of the stroke, the strain is partly taken up by theresilient member and the leverage is increased toward the end of thestroke. The first part of the stroke earries the presser to or towardthe mop without any change of the arm and link from their extendedposition. \Vhen resistance is met one slides on the other against theforce of the spring, which is strong enough to press the water from themop, while the spring obviates the jar and strain which would be felt inthe machine and by the operator in case there was an unyieldingconnection of the parts of the operating mechanism. The construction ofthese parts is shown in a variety of forms. ln Fig. .l the shaft has twoarms. 20, each slotted. the links 21 being suitably engaged therein, 24'being a coil spring on each arm against which the link bears when theshaft is swung by the handle 25 to advance the presser. In this figureis shown an additional resilient member, which may be used asalternative to the other means or in conjunction with either of them. Itconsists in 'ay 21' on each side adapted to carry block 27 in which theshaft is supported. The. way is slotted at 28, Fig. 2, to allow travelof the block. Between the block and the head of the way is the resilientmember, here spring 29, with screw 30 with collar 31 hearing against oneend of the spring whereby to regulate the tension of the spring. InFigs. 3 and 1 the arms 20 are closer together and a cross-head 10 ismounted on them, the link 21 being connected to the cross-head to allownecessary play of the parts when the shaft is rotated. in Fig. 5 the arm20 is shown as slotted and provided with the spring 21", while in Fig.(3 arm 20" and link 21 are both slotted (with a bolt +13 connectingthem) and shown with a spring 21 on each. In Fig. 7 the arm 20 and thelink 21 are shown as having a collar and 4-1 each with a spring 24, thecollars being pivotally connected, for instance, to allow adjustment,each collar bearing against a spring which is carried by its respectivemember, each collar being adapted to slide on its carrying member (armor link.) In Fig. 10 the shaft C is shown with arms 20 at differentangles on the shaft with two links 21 extem ed to the lower part of thepresser and the link 21 from the other arm 2O extended to a point nearthe upper part of the presser. Each arm is shown with spring 2& asbefore. In this style the top opens a greater distance than the bottom,making it convenient for inserting the mop. The pressure is alsoequalized between the arms adapting the presser to crowd against the mopmore in conformity to its bulk as it lies between the pressing members.Of course, these are merely illustrative of different methods of formingthe operating parts and selection may be made of general features, invarious combinations, or equivalent devices may be employed.

It will be seen that in this device I provide members for crowding thepresser against the mop which have a sliding connection, so that as thepresser approaches the. end of the stroke where the greatest pressure isnecessary, the leverage is increased, the connection between themembers, which is the bearing between them, changing its position so asto give greater leverage at the handle for exerting necessary pressure.Soon after their bearing point moves from its normal position, onemember (or set of members) bears against a spring (or both do as thecase may be). In case a large mop is used the compression begins at anearly moment, the presser adapts itself (also the presser-back) to theshape of the mass to be compressed, and as the presser is advanced thepower of leverage becomes greater and soon one member bears against aspring which prevents the presser from falling back from the work by thebearing between the arm and the link at once sliding to the limit, butas full a stroke as necessary is allowed. The strength of the spring isgreat enough to effect the wringing of the mop at any point, when thenecessary pressure is applied. In case of a small mop the arm and linkswing a greater degree before the presser bears on the mop or thebearing point is changed. Vhen pressure is begun, however, the bearingpoint gradually changes as the spring yields in exerting pressure on themop according to its tension or stiffness. Adequate pressure can be madeon either a large or a small mop, the presser and presser-back adaptingtheir planes, respectively, to the form of the mass.

In the form shown in Fig. 10 it is intended that the construction shallhave a plurality of such appliances cooperating to effect continuous anddistributed pressure.
